Ingredients
For the pasta + sauce
- 1 lb spaghetti
- 1 lb ground beef
- 1 jar (24 oz) marinara sauce
- Salt, to taste
- Black pepper, to taste
For the creamy filling
- 8 oz cream cheese, softened
- 1 cup cottage cheese
- 1 cup sour cream
- ½ cup grated Parmesan cheese
For topping
- 2 cups shredded mozzarella cheese
- ¼ cup butter, sliced (for those classic buttery pockets on top)
Swaps and Notes
- Ground beef alternatives: Ground Italian sausage, turkey, or a beef/pork blend all work beautifully.
- Cottage cheese substitute: Ricotta is a perfect 1:1 swap if that’s what you have.
- Add veggies: Stir in sautéed mushrooms, spinach, or diced bell peppers to the meat sauce.
- Spice it up: Add red pepper flakes, a pinch of cayenne, or a spoonful of Calabrian chili paste if you like heat.
- Choose your marinara: A basil-forward sauce is great here, or go garlicky if you want deeper flavor.
Step-by-Step Instructions
- Preheat + prep: Heat oven to 350°F (175°C) and grease a 9×13-inch baking dish.
- Cook spaghetti: Boil spaghetti until al dente (slightly firm). Drain and set aside.
- Brown the beef: In a skillet over medium heat, cook ground beef until browned. Drain excess fat.
- Simmer the sauce: Stir marinara into the beef and simmer 10 minutes. Season with salt and pepper.
- Make creamy filling: In a bowl, mix cream cheese, cottage cheese, sour cream, and Parmesan until smooth.
- Layer #1: Add half the spaghetti to the baking dish.
- Creamy middle: Spread the cheese mixture evenly over the spaghetti.
- Layer #2: Add remaining spaghetti on top.
- Sauce it: Pour the meat sauce evenly across the top.
- Finish + bake: Dot with sliced butter, sprinkle mozzarella, cover with foil, and bake 30 minutes. Uncover and bake 10–15 minutes until bubbly and golden.
- Rest: Let it sit 10 minutes before slicing (this helps it hold its shape).
Tips for Success
- Don’t overcook the pasta. Al dente is essential so it doesn’t get mushy after baking.
- Soften the cream cheese fully for a smooth, spreadable filling (no lumps).
- Rest before serving. It’s tempting to dig in immediately, but a short rest makes cleaner slices.
- Use freshly shredded mozzarella if you can—melts better than pre-shredded.
- Double it for a crowd: This recipe scales well. If you’re feeding more than 4, make a second pan or increase portions.
Serving Suggestions and Pairings
This casserole is rich and cheesy, so pairing it with something fresh and crunchy is the move:
- A crisp, garlicky salad like Easy Homemade Caesar Salad with Chicken balances the creamy layers perfectly.
- For potlucks and family gatherings, serve it alongside Easy Classic Pasta Salad for Any Gathering to stretch the meal and add a lighter bite.
- If you’re planning lunches for the week, round things out with something handheld like The Ultimate Turkey Club Wrap for Easy Lunches.
And if you’re going full comfort-food mode, this casserole pairs amazingly with warm garlic bread or a simple sautéed green veggie (broccoli or green beans are perfect).
